It might have been half-an-hour, perhaps even an hour (for I could take but imperfect note of time) before I again cast my eyes upward. What I then saw, confounded and amazed me. The sweep of the pendulum had increased in extent by nearly a yard. As a natural consequence, its velocity was also much greater. But what mainly disturbed me, was the idea that it had perceptibly descended. I now observed— with what horror it is needless to say—that its nether extremity was formed of a crescent of glittering steel, about a foot in length from horn to horn; the horns upward, and the under edge evidently as keen as that of a razor. Like a razor also, it seemed massy and heavy, tapering from the edge into a solid and broad structure above. It was appended to a weighty rod of brass, and the whole hissed as it swung through the air.

I could no longer doubt the doom prepared for me by monkish ingenuity in torture. My cognisance of the pit had become known to the inquisitorial agents —the pit, whose horrors had been destined for so bold a recusant as myself—the pit, typical of hell, and regarded by rumour as the Ultima Thule of all their punishments. The plunge into this pit I had avoided by the merest of accidents, and I knew that surprise, or entrapment into torment, formed an important portion of all the grotesquerie of these dungeon deaths. Having failed to fall, it was no part of the demon plan to hurl me into the abyss; and thus (there being no alternative) a different and a milder destruction awaited me. Milder! I half smiled in my agony as I thought of such application of such a term.

What boots it to tell of the long, long hours of horror more than mortal, during which I counted the rushing oscillations of the steel! Inch by inch—line by line—with a descent only appreciable at intervals that seemed ages—down and still down it came! Days passed—it might have been that many days passed— ere it swept so closely over me as to fan me with its acrid breath. The odour of the sharp steel forced itself into my nostrils. I prayed—I wearied heaven with my prayer for its more speedy descent. I grew frantically mad, and struggled to force myself upward against the sweep of the fearful scimitar. And then I fell suddenly calm, and lay smiling at the glittering death, as a child at some rare bauble.

There was another interval of utter insensibility; it was brief; for, upon again lapsing into life, there had been no perceptible descent in the pendulum. But it might have been long—for I knew there were demons who took note of my swoon, and who could have arrested the vibration at pleasure. Upon my recovery, too, I felt very—oh, inexpressibly—sick and weak, as if through long inanition. Even amid the agonies of that period the human nature craved food. With painful effort I outstretched my left arm as far as my bonds permitted, and took possession of the small remnant which had been spared me by the rats. As I put a portion of it within my lips, there rushed to my mind a half-formed thought of joy—of hope. Yet what business had I with hope? It was, as I say, a half-formed thought—man has many such, which are never completed. I felt that it was of joy—of hope; but I felt also that it had perished in its formation. In vain I struggled to perfect—to regain it. Long suffering had nearly annihilated all my ordinary powers of mind. I was an imbecile—an idiot.

The vibration of the pendulum was at right angles to my length. I saw that the crescent was designed to cross the region of the heart. It would fray the serge of my robe—it would return and repeat its operations —again—and again. Notwithstanding its terrifically wide sweep (some thirty feet or more), and the hissing vigour of its descent, sufficient to sunder these very walls of iron, still the fraying of my robe would be all that, for several minutes, it would accomplish. And at this thought I paused. I dared not go farther than this reflection. I dwelt upon it with a pertinacity of attention—as if, in so dwelling, I could arrest here the descent of the steel. I forced myself to ponder upon the sound of the crescent as it should pass across the garment—upon the peculiar thrilling sensation which the friction of cloth produces on the nerves. I pondered upon all this frivolity until my teeth were on edge.

Down—steadily down it crept. I took a frenzied pleasure in contrasting its downward with its lateral velocity. To the right—to the left—far and wide— with the shriek of a damned spirit! to my heart, with the stealthy pace of the tiger! I alternately laughed and howled, as the one or the other idea grew predominant.
